March23, 2012

With the domestic industrial trends shifting towards high added values and high quality over ppm order, demands for highly functional equipment cleanliness with low investments are increasing.

(1) Technology elements required for clean compatible designs

Principles of creating and maintaining clean environments are the following 3.

Do not bring in contamination.
Do not generate contamination.
Do not allow contamination to accumulate.

The elemental technologies to form and maintain each one of the principles on LCA mechanisms would be as follows.

[Table 1] Main technological elements comprising the 3 principles of cleanliness

3 principles of cleanliness	Elemental technology	Explanation
[1] Do not bring in contamination.	Filtering technology	Remove contamination with filtering
	Washing / Packaging technology	Packaging to bring in after removing contamination
	Atmospheric pressure control technology	Macro air flow control to maintain clean environments
	Air flow control technology	Micro air flow control technology to maintain clean environments
	Measure and evaluation technology (common)	Contamination amount measurement technology Air pressure / flow measurement technology
	LCA design technology (common)	All LCA design technologies
[2] Do not generate contamination.	Friction / wear reduction technology (Lubrication technology)	Technology to reduce particles from moving slide parts
	Materials technology	Corrosion resistant materials, Static electricity control materials, Sealing materials, etc.
	Packaging technology	Packaging
	Measurement evaluation technology	Same as [1]
	LCA design technology (common)	Same as [2]
[3] Do not allow contamination to accumulate.	Static control technology	Reduction of contamination accumulation by static charges
	Air flow control technology	Reduction of contamination scattering by floating
	Cleaning (Cleaning technology)	Removal of accumulated contamination
	Measurement evaluation technology (Common)	Same as [1]
	LCA design technology (common)	Same as [2]
